PRETORIA, South Africa — A prison social worker thinks Oscar Pistorius’ punishment for shooting his girlfriend dead should be three years’ house arrest at his uncle’s mansion while he performs community service of “cleaning duties’’ at a museum or hospital for 16 hours a month.

And he’d be able to continue his athletic career.

The testimony of Joel Maranga at the “Blade Runner’s’’ sentencing hearing Monday outraged prosecutor Gerrie Nel, who called the recommendation “shockingly inappropriate.’’

Judge Thokozile Masipa found the double amputee guilty last month of culpable homicide, the equivalent of manslaughter.

Proceedings resume Tuesday. The judge will pronounce sentence after hearing from at least three witnesses — one more for the defense, and the others for the prosecution.

She can sentence Pistorius to anything from a fine to 15 years in prison.
